Undeletable folder that makes limewire restart after I exit from it...
 

I dunno if its a folder but the picture for it is a folder and the name is "_" and the name is in red which makes it look even more menacing....and wen I go to the "my computer" folder it isnt even there....I unistall limewire and reinstalled it and in a couple days that folder was there again and limewire was acting up again....
